Description
Function NextLayer returns a handle to the next layer in the document after the referenced. If the end of the list has been reached, the function returns NIL.
FUNCTION NextLayer(
h :HANDLE) : HANDLE;
def vs.NextLayer(h): return HANDLE
Parameters
h HANDLE Handle to layer.
Example
If you need to traverse all objects in the document, you'll have to traverse all layers and then list the objects in each one:
VectorScript
PROCEDURE ListDocument; VAR hLayer, h : HANDLE; BEGIN hLayer := GetParent( FObject ); WHILE hLayer <> NIL DO BEGIN h := FInLayer( hLayer ); WHILE h <> NIL DO BEGIN AlrtDialog( Concat( 'h=', h, ' type=', GetTypeN(h) ) ); h := NextObj( h ); END; hLayer := NextLayer( hLayer ); END; END; Run(ListDocument);
Python
def ListDocument(): hLayer = vs.GetParent( vs.FObject() ) while hLayer != None: h = vs.FInLayer( hLayer ) while h != None: vs.AlrtDialog( vs.Concat( 'h=', h, ' type=', vs.GetTypeN(h) ) ) h = vs.NextObj( h ) hLayer = vs.NextLayer( hLayer ) ListDocument()
